formed in the under side of the bar D at such an angle that the teeth will project backward in the line of draft of the cultivator, and are secured therein by means of bolts K, which pass through the bar and are curved at their lower ends in such manner as to be adapted to encircle the ends ot' the teeth J, as best shown in Fig. 5. The curved ends of the bolts K are adapted to enter holes suitably placed in the under side of the bar D, and the bolts K are provided at their upper ends with nuts 7c, by means of which the bolts may be drawn upward to tightly clamp the teeth against the bar D. In order to further secure the teeth in place they are each provided at their upper ends with a short. upward projection j, adapted to enter a suitable hole in the under side of the bar, as best shown in Fig. et. To rigidly secure the teeth J in place, two bolts K should be used t'or each tooth, as indicated in the drawings. 'lhe teeth .lare provided at their lower ends with shovels L, which ar'e of the usual construction and are secured to the teeth in any suitable manner.

While the round teeth herein described are more particularly adapted for use on cultivators, we do not wish to limit our invention 4to cultivators alone, as it may be applied t0 produce a straddle-row cultivator, or with several sections to produce a barrow.

That we claim as our invention, and desire to secure by Letters Patent, is

l. A cultivator consisting of a beam B, a cross-bar D, carrying spring-teeth J, having attached shovels L, a clamp F, resting upon the cross-bar and engaged with a part of'the beam, the clamp F', resting against the upper side of the beam, and the bolts b, passing vertically through the cross-bar and the clamps at opposite sides of the beams, substantially as described.

2. A cultivator consisting of a cylindrical beam B, a cross-bar D, carrying spring-teeth .l havin gattached shovels L, a clamp F, resting on the cross-bar, engaging a part of the beam and having a curved sea-t in which the beam rests, the clamp F', arranged above the beam and having a curved seat therefor, and bolts Y), passing vertically th rough .th-e cross-barand the clamps at opposite sides of the cylindrical beam, substantially as described.

3. rlhe combination, with a circular beam B, having a projection H on its under side, bar D, and teeth J, secured to said, bar, of clamps F F, adapted to secure the bar D to the beam B, said clamp F being provided with an indentation adapted to receive the projection H, substantially as and for the purpose specified. l
